I'm afraid I don't know much about the genetics involved in the salmon color but I found a thread here that involved trying to get a blue wheaten silkied ameracauna starting with blue silkied ameracauna crossed with regular non silkied wheaten ameracauna. Seeing as salmon is silver wheaten perhaps you could infer a bit on a breeding program to try to create your silkied faverolle? I'm sure it'll be a much longer project as you'll have to get back to the faverolle type while keeping the silkie feathering but perhaps it's a good place to start?
Seeing as you aren't aiming for blue and you'll need a silver based bird perhaps a silver based black silkie rooster over faverolle hens might work as a starting point. The pure silkie offspring from the two lighter colored silkie hens will be mix colored but should still make nice pets.
